This article describes a feature in the first Apocalypse Rising
The Hero Badge was removed from the game.
The Hero Badge was the hardest to earn out of the three first-stage badges (Bandit, Survivor and Hero). You will need to kill three bandits, (players who killed innocent players) and survive for 3 days. Once you got an aggressive kill (a kill on a non-bandit), your Hero run would be over. Obtaining the Hero Badge gave you a blue headband.
